we have designed Low Power RF board based on CC1121, and characterized it for its performance. The Unmodulated-Continuous-Transmit is working fine, similarly the Continuous-Receive is working fine. As a next step i wanted to test the board for packet transfer (PER), so taken two CC1121 boards, configured one board as Pactet-TX and another board as Packet-RX, and ensured, data rate, modulation, RX filter BW, frequency of operation are same. once the receiver board is started and then the transmitter board was started, the transmitter board does not send more number of packets than 3-packets. (Please find the error message attached in word format).
Then observed Modulated-Continuous-Transmit to work fine for all modulation formats in the Signal Analyzer.
Also the Contiuous-Receive works fine when power fed from Signal Generator.
But the Packet -Tx & -Rx is not working.
Any suggestion to with proper resoning would be of great help.
P.S: I have followed the schematics as given in Ti-website and double checked on the values and connections.
Thanks,
Kamesh Kumar
